Hi all,

I got a second hand cranking grinder this past weekend, and this one will actually fit a 6" wheel. It's hard to find a decent 5" wheel for my old grinder really anywhere, so I was on the lookout for a replacement and found a nice one.

The problem: most hand-crankers have a 3/8" arbor. No one makes a decent wheel suitable for grinding hand tool irons with a 3/8" hole. They're normally 1". I don't have a lathe or I'd make my own, so does anyone know of a source to get ahold of a 1" to 3/8" x 1" thick reducer bushing? I can imagine there are probably several people here with something similar going on but I didn't find this in search, so I thought it might be worth asking.

Incidentally, I have been to Grainger, Home Depot, Menard's, and McMaster-Carr already. None of them sell one this size.

Thanks,
GC

The wheel isn't moving that fast. Why not take a 1 in oak or maple dowel cut the the right length and drill a 3/8 hole in the middle? Not elegant but I'd give that a try first.

I can make you a bushing. PM me about it. Need to know width of wheel,size hole in wheel.

Have you looked at your hardware store? Mine has a selection of nylon bushings. I don't know if any are that size, but I could put it on my list to check if you need.

2 bushings? 3/8 X 3/4 inside 3/4 X 1?

Wow, somehow I didn't see the replies.

Making one myself will require I use my drill press with its questionable bearings as a lathe. It's not an ideal solution but it was on the table. I might do that to make a knob for one of my planes in need of resto..or I might save my cash for a little bit and buy a small lathe. Not now though.

George I will PM you as soon as I scrounge up a wheel so that I can get final dimensions.

And then after I buy a lathe I might consider making a ton of these and sell them on ebay..haha!

Try an auto parts store. Look at the fuel line hose. you might find something to fill the gap. it might cost you a quarter, you will only need an inch or so.

why not drill your 3/8 hole in a peace of wood. Mount that on the grinder and use the grinder like a lathe to get it down to the size you need.

Glen; Check out a bearing distributor, not home depot.http://www.houstonbearing.com/products/BEARINGS/BRONZE%20BUSHINGS.aspx?category=BRONZE-BUSHINGS

You can find all the bushings in different sizes your heart desires. I have over the years, having been a eq. mechanic, needed to put a bushing in something in order to repair it instead of replacing it. I don't remember what state you live in, but there are bearing distributors like Houston bearing in almost every major city.

Sears USED to sell a group of red plastic bushings stuffed one inside the other. Pretty sure they went down to 3/8"

But,I'll make you one for the postage.

Wow, lots of advice. I couldn't find a bearing that might work on that site though the thought of a bronze one did sound pretty cool.

I might take you up on your offer George just so thay I can say I had a custom bushing made that I didn't make myself! I'll see if I can come up with a wheel soon and PM you. Or, I might just go with a stock 6x1x1 norton white wheel. They're only about $22 or so and are uniform in size, so if it fit one wheel it'll fit 'em all. Material for the bushing isn't important..wood, aluminum, bronze, nylon.

The only reason I have for not making one myself is that I don't think I have a good way of guaranteeing concentricity with the drilled hole that doesn't involve side pressure on the drill press.

I have plenty of brass on hand. Brass is best.,though plastic would be fine,in reality. Don't make one of wood. If it gets wet,it could swell enough to crack the wheel. A steel bushing would get rusty and jam in the wheel if it got wet.

Brass is nice. You have a metal lathe?
